She may be a silver screen star with a wardrobe that is the envy of women twice her age, but young starlet Chloe Moretz, 15, is clearly still a little girl at heart.

The Dark Shadows star was pictured sweetly holding hands with her big brother Trevor as they crossed the road in downtown Los Angeles yesterday.

The 15-year-old actress who is usually seen in an array of designer looks was in dressed down mode as she held hands with Trevor, who also doubles as her acting coach.

Looking younger than her 15 years for once, Chloe looked age-apropriate in jeans and a T-shirt as they ran errands in LA.

It is a far cry from the young actress's usual designer look, which has seen her grace many a best dressed list even at her tender age.

Recently Chloe who starred in Kickass and recently premiered Dark Shadows in London appeared on The Ellen DeGeneres Show.

She explained that when it comes to choosing her film roles, the often dark characters tend to be nothing like her.

She said: 'I’ve done some kid stuff, but I mean I’m just driven to do stuff that is not ‘me,’ you know?

'I just had a meeting with a director and I have three pages of notes on the psychology of the character and her thoughts and her past. It’s, like, as complicated as genetics.'

Moretz is set to take the lead role in the highly anticipated remake of Brian de Palma's Carrie which is set to be 'darker and more psychological' than the original 1976 horror film.

Trevor tweeted: 'Time for a little #carrie character study,' referring to Chloe‘s new movie.

She will play the titular role of a bullied schoolgirl who discovers she has psychic powers and uses them to cause havoc in her hometown - and revealed the movie will have similarities to 2010 psychological thriller Black Swan.

She said: 'It's darker and much more psychological. More Black Swan. You're really looking into her mind and it really looks into the relationship of Margaret and Carrie.

'It's set in modern time, so it's a lot different.'

Theremake will take more inspiration from the Stephen King novel of the same name. Julianne Moore will take the Piper Laurie role as Carrie's mother. Sissy Spacek played the original Carrie.

She admitted: 'I'm actually not looking at the original, even though De Palma's movie was one of the best movies ever made.

It's completely iconic and I'm proud to be able to be doing a retooling of it. We're kind of going off the book.'
